Overview

The Range of Light Trail Races take place in the Eastern Sierra near Bishop, California. The event is a fundraiser for Inyo County Search and Rescue. It offers four trail running distances: 5 km, 10 km, 33 km, and 50 km. The courses start and finish at the Millpond County Recreation area. Same-day registration is available on-site for the 5k and 10k distances, but not for the 33k or 50k.

The Courses

  • The 5 km is described as a fun, family and pet-friendly loop from Millpond.
  • The 10 km is a loop that ventures into the Tungsten Hills, featuring a significant hill. It includes a section of single-track trail.
  • The 33 km and 50 km routes leave Millpond and traverse the Tungsten Hills on dirt roads and single-track trails. They feature significant climbing, with the 33k course diverging from the 50k course at the mile 16 aid station. The 50k route continues for a longer tour of the hills.

Aid Stations

Aid stations offer fruit, salty snacks, and at some locations, heartier food like pancakes and quesadillas. The finish line provides an end-of-race meal. Specific aid station counts are:

  • 5k: No aid stations.
  • 10k: 1 aid station.
  • 33k: 5 aid stations.
  • 50k: 8 aid stations.

Logistics
